The color stability of resin cements is essential for aesthetic restorations. Aim: To evaluate the influence of shade and aging time on the color stability of two light-cured and two dual-cured resin cements. Methods: The CIE-Lab color parameters (n=6) were measured immediately after sample preparation and at 7, 30 and 90 days of aging in distilled water. The color difference (∆E) was calculated and then analyzed by three-way ANOVA for repeated measures and Tukey's HSD test (α=0.05). Results: ∆E was higher for transparent resin colors, followed by dark and light colors. The mean values of ∆E were lower for both light-cured resin cements compared to the dual-cured cements. As the aging time increased, ∆E values increased. Conclusions: The light-cured resin cements showed greater color stability. The lighter shades of luting were more likely to display a greater color change.

“…Dual cured resin cements are generally used for luting thin and translucent restorations so color stability is needed (17). Both intrinsic and extrinsic factors leads color change in resin materials (10,15,(18)(19)(20). Intrinsic factors are material related (15).…”

Bulgular: En düşük ΔE değeri grup 1'de gözlendi. Grup 2'de, grup 3'e kıyasla daha yüksek ΔE değeri elde edilse de her iki grup arasında istatistiksel olarak anlamlı fark bulunamadı.Sonuç: Yarı saydam baz ve yarı saydam katalizör karışımı sonucunda klinik olarak kabul edilebilir bir renk değişimi gözlenirken, B1 baz, A3 katalizör ve A1 baz, A3 katalizör karışımları ise klinik olarak kabul edilebilir değerlerin üzerinde renk değişimi göstermiştir. Rezin simanın rengi simanın renk stabilitesi üzerinde kısmen etkili olmuştur. Objective:The aim of this study was to determine effect of shade selection on resin cement's color stability. MaterialsandMethods:Ten resin cement samples in dimensions of 10 mm diameter and 2 mm thickness for each group [group 1: Translucent base and translucent catalyst, group 2: Bleach XL (B1) base and yellow (A3) catalyst, group 3: White (A1) base and A3 catalyst] totally 30 samples were prepared. Color coordinates of each sample were recorded after polymerization and 5000 thermal cycles. Color variation (ΔE) was calculated for each sample and statistical analyses were performed. Results:The lowest ΔE values were obtained for group 1. Group 2 showed higher ΔE values than group 3 however there were no statistical difference. Conclusion:Translucent base and translucent catalyst mixture showed clinically acceptable color stability while B1 base and A3 catalyst and A1 base and A3 catalyst mixtures did not show clinically acceptable color stability. Shade of the resin cement partially effected its color stability.Ad dressforCor res pon den ce/Ya zış maAd re si:

Objective: The aesthetics of dental materials is extremely important for the success of oral rehabilitation. Thus, in the present study we evaluated the color stability and the surface degradation of three micro hybrid composite resins after accelerated artificial aging process (AAA). Methods: Were prepared 24 specimens (n=8) for each material: Solidex, Artglass and Cesead, dimensions of Ø 15 mm by 2 mm in thickness. The samples were subjected to color analysis, before and after AAA, in a spectrophotometer according to the CIE L*a*b* parameters, and a sample of each material, was selected for morphological evaluation under scanning electron microscopy (SEM). The data were submitted to one-way ANOVA and Tukey test (α=0.05). Results: Artglass showed higher stability regarding the presence of red and yellow (p<0.05) when subjected to the AAA and fewer of these pigments (p<0.05) when compared to the Cesead and Solidex, which showed the highest luminance stability (p<0.05). ΔE Cesead was the most unstable (p<0.05). All resins analyzed by SEM showed superficial degradation when submitted to the AAA, mainly in resin Cesead. Conclusion: All materials analyzed demonstrate color change and surface degradation, Cesead resin showed the worse results.
